Struct StepId 

pub struct StepId(/* private fields */);

Opaque per-step identifier, e.g. ST-<hex>. Newtype over String so step, session, and worker ids can’t be swapped by accident at call sites.

One StepId is minted per dispatched Blueprint step (the engine’s dispatcher “spins up a fresh task per Step.ref”). It is scoped to a single step execution — the whole-kick identity is RunId, and the work-item identity is TaskId.

Renamed from TaskId (T- prefix) in the issue #13 ID-hierarchy reconciliation: Blueprint → Task → Run → Step → Attempt.

Implementations

impl StepId

pub const PREFIX: &'static str = "ST-"

The prefix this ID kind carries on the wire.

pub fn new() -> Self

Mint a fresh id with the kind prefix and a process-unique nonce (see uid_hex).

pub fn parse(s: impl Into<String>) -> Result<Self, IdParseError>

Parse an externally-supplied string, rejecting values that do not start with the kind prefix or carry nothing after it.

pub fn as_str(&self) -> &str

View the id as a string slice.

pub fn into_string(self) -> String

Consume the id and return the inner string.

Trait Implementations

impl AsRef<str> for StepId

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for StepId

fn clone(&self) -> StepId

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for StepId

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for StepId

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for StepId

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for StepId

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for StepId

impl From<StepId> for String

fn from(id: StepId) -> String

Converts to this type from the input type.

impl FromStr for StepId

type Err = IdParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, IdParseError>

Parses a string s to return a value of this type.

impl Hash for StepId

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for StepId

fn eq(&self, other: &StepId) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for StepId

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl StructuralPartialEq for StepId

impl TryFrom<String> for StepId

type Error = IdParseError

The type returned in the event of a conversion error.

fn try_from(s: String) -> Result<Self, IdParseError>

Performs the conversion.
